CARTON Filed Sept. 25, 1926 2 Sheets-Sheet 1 vPatented May 20, 1930PATENT OFFICE MILTON HINKLEY, F BENTON HARBOR, MICHIGAN CARTONApplication filed September 25, 1926. Serial No. 137,639'.

This invention relates to cartons in general, but more particularly toegg cartons and fillers therefor, of the kind in which a dozen eggs aresold at the stores. Ordinarily, these cartons are made to collapse orfold flat,so that they may be conveniently stored or shipped.

Generally stated, the object of the invention is to provide a form ofcarton which will nest one within another, to form a compact stack ofcartons for storage or shipment, With a flexible cover integral with therear side Wall of each carton, the covers being also preferably adaptedto nest together at one side of the stack, thus obviating the necessityof using a foldable or collapsible construction for an egg carton ofthis character, the invention in this case being in the nature of animprovement on the construction shown and described and claimed broadlyin prior application Serial No. 127,267, filed August 5, 1926.

To the foregoing and other useful ends, the invention consists inmatters hereinafter set 25 forth and claimed and shown in theaccompanying drawings in which Fig. 1 is a perspective of an egg cartonand filler involvingthe principles of the invention, showing the coveropen.

Fig. 2 is a transverse section of said carton and filler, showing thecover closed.

Fig. 3 is a longitudinal vertical section on line 3-3 in Fig. 2.

Fig. 4 is a plan view of the blank from which the carton is made. I v

Fig. 5 is a transverse section of a stack of nested cartons.

Fig. 6 is a perspective of one end portion of the carton, in partiallyfolded condition.

As thus illustrated, the blank comprises the bottom section 1, rear sidesection 2, front side section 3, the cover section 4, and the cover flapsection 5, as shown in Fig. 4 ofthe drawings. For the formation of theend walls of the carton, the blank also'has the sections 6, 7, 8, 9 and10 at each end thereof. It

will be seen that the score lines or creaselines 12, 13, 14, 15, 16, 17,18, 19, 20, 21 and 22 are so located as to form the different sectionsof the blank as shown and described,

to obviate the cutting through of the mate rial, and to form strongerend walls'for the carton, as will more fully appear.

lVhen the blank is folded, the different sections thereof assume thepositions shown in Fig. 1 of the drawings, and a single staple 23 isinserted through the. folded end wall portions, at each end of thecarton, thereby to hold the blank in its folded condition.

When the carton is thus completed, the front and rear sides 3 and 2 areinclined outwardly, as shown in Fig. 2 of the drawings, and the endwalls'of the carton are'also inclin d outwardly, as shown in Fig. 3ofthe drawings. But because there are no cuts in the blank, and onlyscore lines or crease lines, there are no cracks or crevices anywhere,and the carton ispractically leak-proof, as any liquid if placed in thecarton could not leak out. And, in addition, the scoring-or creasing ofthe blank is comparatively simple and inexpensive, and the blankthusformed folds readily and easily, and the end walls are strong andstiff and the box or carton is serviceable. V I

The cartons'when thus made can be nested as shown in Fig. 50f thedrawings, for shipment or storage, in an indvantageous manner. This isbecause, as illustrated in Fig. 6, which shows one end of the cartonpartial 1y folded, the form of the blank and the fold,- ing thereofserve to produce a downwardly tapered carton or box, the sides and endsbeing inclined outwardly, and'hencethe car'- tons orboXes of this kindare advantageously nested and stacked as shown.

The filler 24, shown in Figs. 1, 2 and 3, can be of any suitable knownor approved form, being of a size to accurately fit the bottom of thebox or. carton, so that thefillercannot shift sidewise or endwise. Butbecause the walls of the cartonor boX are inclined outwardly, there willbe some space between the upper edges of the front and rear sides of thebox and the adjacent sides of the filler, and 95 some space between theends of the filler and the upper edges of the end walls, as Y shown inthe drawings. Thus the end walls of the carton are formed from sheetmaterial which is-not cut i ixer 9,45% J f I i ;x

V or severed at any pint, the material being I merely folded and doubledback upon itself,

and the end walls being thus formed ofsections of sheet material havingonly fold lines between them. The sections 7, 8 and 9, at each end ofthe carton, thus form upwardly tapered outside end portions of doublethickness, as the sections 7 and 9Vare folded against the inner surfaceof the section 8 at each endof the carton.

Without disclaimm'g anything, and with 1 out prejudice to any noveltydisclosed, what i I claim as my invention 1s:

. 1. In a carton formed from asingle blank,

the combination of flat end Walls inclined outwardly, flat front andrear side walls inclined outwardly at an angle, a flat bottom wall, anda flexible rectangular cover integral with the rear side wall,wherebyeach carton body isrectangular at top and bottom and shaped to nest onecarton within an other, to form a stack ,ment or storage, with the coverof each carton o forming an overlap inside each end wall, withprotruding from theside of the stack, said end walls being. formed ofsheet material folded and doubled back upon itself and creased toobviate cutting through the ma terial andto form strongerend walls toprotect V the contents of the carton, providing inside overlapping flapshaving straight end edges, and an outside upwardly tapered flap of morethan one thickness for each end of the carton,

' the straight upper edge of reach outside flap necessarily positionedflush with the straight upper edges of the inside flaps in the foldingofthe blank to obtain said inclined angle of the front and rear walls,said inside end edges extending downward-from the top edge of each flapto points below, with theoverlap between these two edges at each end ofthe 1 box, and with each outer flap wide enough to o a fillenfor eachcarton, when the carton is released. from the stack for use, adapted tocover the entlre overlap, each inside flap comprising only a singlethickness of the blank,

of cartons for ship- 5. A structure as specified in claim 1, hav ingmeans forming the contents thereof, said cover having a flap forinsertion lnside the outwardly inclined front side wall, thisfront sidewall and the adjacent sidefof the con tents forming in cross section adownwardly tember, 1926.

whereby said overlap is of double thickness only.

2. A structure as specified in claim 1, and

rest on said bottom between said outwardly inclined side and end walls.P 3. Ast'ructure asspecified'i'n claim 1, said cover adapted to nestwith the cover of another'carton, so that the covers are all at the sameside of the stack.

4'. A structure as specified in claim 1,;and

a fillerifor each carton, when the carton is released from the stackforuse, adapted to, I rest on said bottom between said outwardly inclinedside and end walls, said filler having vertical sides and ends, butthelength and width of the filler being substantially the same as saidbottom, whereby thG'lOWGI por tions of the side and end Walls holdthefiller against displacement.
